We use them!!! I have the Sili Squeeze pouch...got it on babysteals.com and DD loves it!!! We use it for smoothies, but I am now realizing that I should totally bring it out in the diaper bag so I can put her apple sauce and yogurt (not together lol) in it so that she can self-feed on the go!

Omg hmboudreau she is so cute! I like the idea of her feeding herself on the go. I believe they are on www.squooshi.com but I don't know if they r available elsewhere. I saw them on twitter and pinterest so I was i intrigued. Thx ladies

They just put up a great sale for these on squooshi.com :) It's usually $19.99 for 4 big pouches or $16.99 for 4 little pouches.
Now they have 4 big + 8 little for $37.50, and you can get 20% off of that with the code 'greengifts20'
Standard shipping is $4.50.
And no, I am not affiliated with squooshi. I am merely excitable :)
